Facebook users flagged it as potentially false, and the headline is not supported by any actual evidence.

The body of the story is based largely on a report from the Daily Star, a British tabloid, that quoted an unnamed “Royal source” saying that former President Obama was invited to the wedding. That report also was published more than a month before the invitations were sent out the week of March 23.

The royal family has not made the guest list public, and a spokesman for the family told us that he doesn’t expect it will be released before the wedding.

The story claiming that Trump “is beside himself with anger” was posted on a network of sites called The Political Voice, and it was shared more than 87,000 times on Facebook. We’ve written about made-up claims from that group of websites before. The sites recently posted a story with a headline wrongly claiming that Ivanka Trump had been fired from the White House.

As for the expectation that an American president would be invited to a royal wedding, we wrote about that in 2011 when Harry’s older brother, Prince William, was about to marry Kate Middleton. Obama, who was in office at the time, was not invited to the ceremony.

In fact, the only instance we found of a sitting president being invited to a royal wedding in the last 75 years was when Ronald Reagan was invited to the wedding of Prince Charles and Diana Spencer in 1981. He did not attend, but Nancy Reagan did.
